Schwarzschild-type solution in an effective gravitational theory with local Galilean invariance
R. R. Cuzinatto, P. J. Pompeia, M. de Montigny +1
We construct a Schwarzschild-type exact external solution for a theory of gravity admitting local Galilean invariance. In order to realize the Galilean invariance we need to adopt…
Galilean Covariance and the Gravitational Field
S. C. Ulhoa, F. C. Khanna, A. E. Santana
The paper is concerned with the development of a gravitational field theory having locally a covariant version of the Galilei group. We show that this Galilean gravity can be used…
Path-integral quantization of Galilean Fermi fields
M. de Montigny, F. C. Khanna, F. M. Saradzhev
The Galilei-covariant fermionic field theories are quantized by using the path-integral method and five-dimensional Lorentz-like covariant expressions of non-relativistic field equ…
Noncommutative Geometry and Symplectic Field Theory
R. G. G. Amorim, M. C. B. Fernandes, F. C. Khanna +2
In this work we study representations of the Poincare group defined over symplectic manifolds, deriving the Klein-Gordon and the Dirac equation in phase space. The formalism is ass…
Generalized Thermostatistics and Bose-Einstein Condensation
H. G. Miller, F. C. Khanna, R. Teshima +2
Analytical expressions for Bose-Einstein condensation of an ideal Bose gas analyzed within the strictures of non-extensive, generalized thermostatistics are here obtained.
Gauge Symmetry in Fokker-Planck dynamics
M. de Montgny, F. C. Khanna, A. E. Santana
Using a Galilean metric approach, based in an embedding of the Euclidean space into a (4+1)-Minkowski space, we analyze a gauge invariant Lagrangian associated with a Riemannian ma…
